Falcons beat writer D.Orlando Ledbetter says of Julio "While his training-camp practice schedule will be limited, Jones plans to be in the starting lineup when the Falcons open the regular season against the New Orleans Saints". There is some concern here as Jones is still recovering from his second surgery on the same foot. Ledbetter mentions both both Jones and WR Roddy White will be well documented in the upcoming HBO "Hard Knocks" series.
It's a situation to monitor but Julio should be good to go come opening day. He can be both your first round pick in redraft and dynasty formats. If you really get nervous about these things, check out Hard Knocks to follow along.
